Precision screw screw supply _ _ Hail Hardware

 Screw by hand pulse generator mobile related gap screw shaft design (the MPG as the gear ratio of 1 × 100, which changes every step motor feed 0.1mm) screw supplied with the dial indicator to observe the relevant movement of the shaft. After the one-way movement accuracy to maintain normal forward movement as a starting point, MPG change every step, the actual distance of the machine axis motion d = d1 = d2 = d3 ... = 0.1mm, indicates that the motor is running well, the positioning accuracy is good. The return to the change machine actual motion displacement can be divided into four stages: ① exhibited for d = 0.1mm> d2> d3 (slope less than 1); ② machine and hand movement distance equal to the reference pulse (slope equal to 1 ), returned to the normal operation of the machine tool body ③ not actually move, showing the most standard Backlash; ④ machine movement distance d1> d = 0.1mm (slope greater than 1); move. Most of the ball screw failure was due to decline in the quality movement, the backlash is too large, mechanical crawling, and other causes of poor lubrication. Optional screw lift motor screw lift in production and life everywhere, especially in some of the work platform. Worm screw lift can be a single use can also fit more than one or steering gear box linkage. Can also be used to manually adjust the motor or other power driven. Optional screw lift motor should be selected with good thermal performance, because the lift needed for work, have good ventilation; for jobs in high-temperature environments straight top-lifting platform should be selected Class F motor insulation; indoor installation screw lift platform, its motor protection rating of not less than IP23, outdoor should reach IP54; if there should be a transparent window using a DC motor screw experts to inspect brushes and commutator; screw lift motor should be dispensed in short within a prescribed torque overload; lift the working environment humidity, the internal heater to be equipped with an alarm or power protection device overheating.
